3. Operating Principle
1)The orchestrated opening and closing of the main valve within the pressure differential principle check valve.
Upon initiating water supply downstream, the gate valve at the outlet gracefully opens, allowing water from the middle chamber to flow downstream. Concurrently, as the outlet pressure P2 decreases, the differential pressure P1 effectively overcomes the spring pressure (PZh). This prompts the piston to glide rightward, as depicted, simultaneously triggering the main valve to open through the quick-opening valve disc mechanism. As the inlet pressure challenges the spring's resistance, the medium effortlessly flows from the outer valve disc edges into the middle chamber, continuing downstream. Increasing flow rates cause P2 to further decrease, compelling the piston to move right until the main valve is wholly open.
When downstream water supply is unnecessary, the outlet water supply valve closes. This action causes the middle chamber's pressure to rise, prompting the piston to shift leftward, as illustrated, until closure.
2) The intricate opening and closing of the pressure differential principle check valve's drain valve.
In adherence to national standards: 'When P1-P2 reaches 14 KPa, the drain valve is designed to automatically activate for drainage. As the pressure differential P1-P2 continues to decline, the drain valve remains active until it fully opens, thus depleting the middle chamber and creating an air gap between the inlet and middle chambers.'
This efficient drainage procedure reduces P2. Once P1-P2 falls below 14 KPa, the valve automatically secures itself, thwarting any backflow threats.
Should P1 persist in its decline under specified conditions, the drain valve will remain open, eventually converting the middle chamber into a vacant space. This ensures an air gap between the inlet and middle chambers, effectively eliminating any risk of backflow under any circumstances.
